What I'm looking for

I'm looking for new technical challenges where I can apply my knowledge and experience while contributing to exciting and impactful projects. I want to work in a collaborative environment that values professional growth and continuous learning. My goal is to find a job where I can add value with my skills and grow together with the team and the company

I am a software developer with more than 13 years of experience, including seven years dedicated to developing high-performance Android applications. My professional journey is marked by a passion for creating technology solutions that combine innovation, usability, and efficiency. I specialize in Kotlin and i have experience with Java. I have experience working with apps in both multi-repository and mono-repository architectures, ensuring code scalability and organization. I am skilled in asynchronous programming (Coroutines, RxJava), dependency injection (Koin, Dagger), and local database integration (Room, Shared Preferences). My technical skills also include Gradle, Retrofit, LiveData, Flows, and testing frameworks like JUnit, Mockito, and Espresso.

Throughout my career, besides improving my technical knowledge, I have developed important interpersonal skills, such as communication, adaptability, and teamwork. I am proud to be a reference in the teams I have worked with, and I am often asked to support colleagues with technical challenges and help them overcome difficulties in their tasks. Also, I have worked as a mentor for other developers, promoting the professional growth of the teams and strengthening collaboration in the work environment.
